Very rarely do you care if you move at 3/4 speed vs full speed, but you definitely care about 0 vs 1/4 - thus, you can stretch the axes accordingly.
All you have to do is square the input, making sure to preserve the sign.

Yes, it's already been tried:

A second note - if this is a first or second year team, my suggestion is, "get used to it."

I'd like to hear from any teams that have implemented closed-loop wheel speed control via encoders connected directly to Jags, on a bot with mecanum wheels.
Also, are any teams using shiftable transmissions (high and low gears) ?
